I guess that´s what the tabloid intend to do - surprise people (including me).
If it´s true, Amy and Blake have met each other now and then during the last few weeks/ months somewhere in London. Since Amy came back from Jamaica recently, the hunt (paparazzi) is on again - with a picture this time! Maybe they greeted each other with a gently kiss at the tapas restaurant - many (good) friends do that (instead of cheek-to-cheek or whatever). Today you can take like 30 (?) snapshots during a three-second-greeting-kiss, and here´s another chapter of the 'remarriage trilogy'. If Amy had answered to that right away, they would have written something different again. In the end it´s all private and we´ll have to wait and see what´s true.
Another good example is about 'Amy looks for a house in Camden' - first they wrote she wanted to live in Camden since it´s her favourite part of London (which is true). Now it´s like the 'new family castle is found'. I mean c´mon now, even the Queen is laughing about tabloids!
